W.- E. WORTHEN. METALLIC SASH! Patented Apr 24 UNITED STATES PATENTOFFICE.

WM. E. WORTHEN, OF NEYV YORK, N. Y.

METALLIC SASH.

Specification of Letters Patent No. 28,030, dated April 24, 1860.

To all whom it may concern:

Be it known that I, WVILLIAM E. VVoR- THEN, of the city, county, andState of New York, have invented a new and useful Metallic Sash, andthat the same is fully, clearly, and exactly set forth in the followingdescription and the drawing making part thereof.

In the drawings, Figure 1 is an elevation of a portion of a sash showingone bar in section. Fig. 2 is a perspective view of a portion of a sash.Fig. 3, a plan of the upper side and Fig. 4c a plan of the lower sidethereof.

My object in making this invention has been to devise a light and cheapmetallic sash, sufficiently strong for all practical purposes, andaffording the requisite support for the panes of glass. The sash is madeby taking as many lengths of flat iron or other metal as may benecessary of about the size and shape of those shown in the drawings ata, a a into each of these pieces are to be cut gains or notches reachinghalf through the iron, care being taken to make the notches of butlittle greater width than that of the iron bars and to space the notchesso that they will be at the points where the bars cross in making aframe. When the bars are thus properly notched one set of them is to belaid in rows at the proper distance apart with the notches upward andthe other set are to be forced down into them in such manner that thenotches of the upper set clasp the iron which lies just below thenotches of the lower set; and it will follow that the notches of thelower set will clasp the iron just above the notches of the upper setand that the two sets will be halved together. The metallic bars willthus form a frame having rectangular or lozenge shaped openings, andeach set will sustain and hold the other set in place. Pieces of sheetiron or other metal are then to be bent by hand or any proper machineryso as to have a cross section substantially like that shown in thedrawings at Z) Z), the essential characteristics of the shape being thatthese pieces 0 c 0 shall embrace the bars a a a, closely and shall swellout so as to form a shoulder against which the panes of glass may rest.These bent pieces are to be cm into lengths that will reach fromcrossing to crossing of the bars, and are to be slipped down over themoccupying the position shown in the drawings, and are to be secured tothe bars in any convenient way, small rivets as represented at (Z (Z d,answering very well.

The sash is now fit to support glass and to sustain itself in shape, butthe bars of one set would separate from those of the other, if pushedinward or outward as the case might be when the sash was in place. Inorder to make the sash secure there are to be stamped or struck up outof sheet metal, corner pieces 7 f f, of sufficient size to cover fourmeeting ends of the bent pieces of sheet metal. These corner pieces orbosses have four arms, and the ends of the arms should be so struck upas to fit closely upon the bent pieces of sheet metal as clearlyrepresented at g, g 9 Figs. 1 and 2. Vhen the useless parts of the metalout of which they are stamped are cut away, two ears or flaps such asshown at f f f Fig. 4 are to be left attached to each arm of the boss,and after the boss is placed in position as shown in the drawings theseflaps are to be bent under the shoulders of the bent pieces of sheetmetal. The bosses thus shaped, fitted and secured in place perform thedouble duty of concealing and protecting the oints at the corners ofeach pane of glass and of holding each set of bars and their attachedpieces of sheet metal so that the one set cannot be pulled or pushedaway from the other.

If desired the sash may be made still stronger by soldering or brazingthe ends of the arms of the bosses to the bent pieces of sheet metal,and I sometimes intend not to use the flaps which when bent act asclasps and to depend upon soldering or brazing only. The sash thus madeis sufficiently strong for all practical purposes, is light and whenproper tools are employed for striking up the bosses and bending thesheet metal shoulders it is comparatively speaking cheap.

I claim as of my own invention The combination of metallic bars, withbent pieces of sheet metal constituting subscribed my name in the cityof New York on this 7th day of March A. D. 1860.
